On the eve of its one-year anniversary, Tasmania Police say they have no new information into the murder of West Coast man, Simon Crisp.
Mr Crisp was murdered at the rear of the Marrawah Tavern in the early hours of July 13 last year.
His death has been the subject of an intensive police investigation.
The state government has also approved a $50,000 reward for information that leads to the arrest and prosecution of the person or persons responsible for Mr Crisp's murder.
Detective Inspector Robert Gunton said that there has been no new information received since the reward was announced, however there are a number of persons who remain of interest to the investigation.
"The investigation into the murder of Simon Crisp is open and ongoing and will remain so until the matter is resolved and the person or persons responsible are brought before the court," Detective Inspector Gunton said.
"I reiterate that investigators believe that others are aware of those responsible for the murder of Simon Crisp and the circumstances surrounding it. It may be that their personal situation to date has not permitted them to contact police.
"We are confident that with the passing of time and changes in personal circumstances will enable someone to provide the information required to finalise this case."
Anyone with information which could assist Tasmania Police with their enquiries should contact Burnie CIB on 6434 5291 or Crime Stoppers on 1800 333 000.
